KorVoca uses GPT-4o mini to analyze your input (even misspellings or L1 words) and securely retrieves the exact Korean word and context.
You can adjust the TOPIK level (1-4) in the Settings screen. This will instantly change the difficulty and length of generated example sentences.
Active flashcards are reviewed using our Spaced Repetition System. Once you master a word (e.g., 180 days interval), it graduates to the Archive vault.
Your flashcards and search history are stored locally on your device using a SQLite database. No personal data is saved on our servers.
Flashcards, SRS reviews, and the Archive work 100% offline. However, searching for new words via AI requires an active internet connection.
